When fortunato lifts a toast “to the buried that repose around us,” his words a. foreshadow what is about to happen to him. b. take on a tone we haven't seen before. c. indicate he is suspicious. d. illustrate the conflict of man vs. man.

the sentence that avoid faulty coordination is:

culture, which is well represented in philadelphia, plays a major role including theatre, music, and the visual arts.
